This invention relates to a condensing apl paratus.

its several constituent parts by a .distilling process.

Other objects of this invention relate to the provision of a condensing apparatus Which shall be efficient in operation, of relatively few and simple parts, cheap to manufacture, easily applied for the purpose intended and simple to operate.

With these and other objects in View as will become hereinafter apparent from a detailed description of the invention, reference is had to the accompanying drawing, wherein- Figure 1 is an elevational diagrammatic view of one form of condensing structure arranged within a closed jacket.

Figure 2 is a like elevational diagrammatic view of a modified form of condensing structure.

Figure 3 is also a like elevational diagrammatic view of a still further modified form of condensing structure.

Referring to the drawing in detail, and first to the form of invention shown in Figure 1, It indicates a cylindrical jacket of any suitable material and size closed at each end. At the upper end Il of the jacket there is provided an inlet nipple I2 to which may be connected a hose or pipe (not shown) from a source of cooling water supply, and at the lower end I3 there is provided an outlet nipple I4 for like connection to a hose or pipe (not shown) through which the water is discharged.

Arranged within the jacket ID are a plurality of condenser units I5, I5a and IED arranged vertically one above the other. All of the condenser units are of the same shape and size. Thus the condenser unit I5 comprises a container portion I5, provided at its top with a vertical central feed tube I6 and at its base with a downwardly and outwardly inclined delivery tube I1. In a like manner the condenser units I5a and I5b are provided respectively with like feed tubes ita, lsb and delivery tubes Ha, ma.

The condenser units are interconnected by the feed tube I6 which extends within the condenser unit Ia'ia through the bottom thereof and is attached thereto in liquid tight engagement in any desire-d manner. In a like manner the feed tube Ilia extends in-to the condenser unit Ib and is secured thereto in the same manner. The exhaust feed tube Ib projects outwardly of the top II of the jacket Ill and is fixed thereto in liquid tight engagement, said tube |612 being either open .to the atmosphere or is adapted to be connected to an exhaust hose or pipe not shown. The delivery tubes Il, Ila and I'Ib project outwardly of the wall of the jacket IIJ as shown in a downwardly inclined direction each being adapted to have attached thereto a suitable hose for conducting the condensed liquid to a proper receptacle or receiver (not shown).

Extending upwardly through the bottom end wall I3 of the jacket I0 and into the lower condenser unit I5 is a primary feed tube I8 communicating with a ask or container I9 in which is adapted to be placed any desired liquid cornpound that is to be broken up into its constituent liquids by a fractional distillation. Thus by the application of heat or a flame to the flask I9 the liquid constituents of the compound therein are vaporized at different temperatures depending upon the boiling point of the various liquids that go to make up the compound. Accordingly the liquid constituent that has the lowest boiling point will vaporize first and being of less density will rise to theuppermost condenser unit Ib where it will be condensed due to the circulation of the cooling water through the jacket, the condensed liquid constituent thereupon flowing out of the delivery tube I'Ib.

In this fashion the other liquid constituents are boiled off or vaporized at higher temperatures and Will-'bel condensed in the other condenser units I5a and I5 for collection at the delivery tubes I'Ia and I'I. As the various vapors are condensed in their respective condenser units, the vapors that rise to the higher condenser units are washed in their passage through the body of condensed liquid constituents in said lower condenser units, thus insuring a more perfect separation of the constituent liquids. It is to be understood that any desired number of such condenser units may be assembled within a jacket as may be found necessary. Vapors not desired for condensation having very low boiling points may be exhausted by passing out of the uppermost feed tube I6b. It is to be further understood that the temperature of the cooling water may be also controlled and varied in the manner well known, to control the condensation of the constituent liquids desired.

In Figure 2 there is shown a modified arrangement of condenser units and water jacket. In this case the condenser units 25, 25a and 25h are arranged vertically one above the other and adjacent one side of the water jacket 20. Connecting the condenser units 25 and 25a is a U-shaped feed tube 26, and connecting the condenser units 25a and 25h is a like U-shaped feed tube 26a. An exhaust tube 2Gb communicates the upper condenser unit 25h with the atmosphere or a collecting chamber (not shown) Extending through the base of the jacket 20 and into the lower condenser unit 25 is a feed tube 28, the lower end of which is to be connected to a flask or container such as I9, see Figure 1. Each of the condenser units 25, 25a and 25h are respectively provided with downwardly inclined delivery tubes 21, 21a and 2lb that project outwardly of the jacket 20; The water jacket 2U is a container of any desired shape and size open at the top and lled with water which may be changed, circulated or agitated in any desired manner. The arrangement shown in Figure 2 operates in the same manner, as that described above with reference to Figure 1.

The modified arrangement of condenser units and water jacket shown in Figure 3 is similar to that of Figure 2 with this distinction that the feed tubes 36, 36a and 3619 are looped in form so as to provide feed tubes of greater length. The condenser units 35, 35a and 35h, delivery tubes 37, 31a and 3119, feed tube 38 and water jacket 30 are similar to that shown in Figure 2.

Having thus described my invention I claim as new, and desire to secure by Letters Patent:

A multiple condenser device comprising a plurality of like elongated single container condenser units each provided with a cup-shaped bottom and top and arranged one above the other in series relation, an elongated jacket containing a cooling medium housing said condenser units, said jacket being of such a size as to provide a substantial space between the walls thereof and said condenser units axially disposed therewithin, a feed tube connecting the top of one condenser unit with the bottom of the next adjacent condenser unit, a primary feed tube extending outwardly of said jacket and connected to the bottom of the lowermost condenser unit, an exhaust feed tube connected with the top of the uppermost condenser unit and extending outwardly of said jacket, said feed tubes, primary feed tube and exhaust feed tube being coaxially disposed with respect to each other and each of said feed tubes projecting axially into its associated condenser unit a substantial distance above the cup-shaped end thereof, and a delivery tube for each condenser unit connected to the cup-shaped bottom of each substantially at its lowermost point, said delivery tubes being inclined downwardly and extending outwardly from the same side of the jacket, said jacket being closed at its top and bottom, an inlet pipe provided at the top of said jacket and an outlet pipe provided at the bottom of said jacket in diagonally opposed relation thereto whereby to provide a constant circulation of cooling medium through said jacket.
